Sexosomnia

I had something really bizarre happen last night. This morning when I was getting dressed for work my wife sits down and says, "I need to talk to you about something." I have no idea what this could be but she asks me if I remember what happened last night. I respond that I didn't. I remember reading and going to sleep and that's all. I know I woke up on the futon in our room which is not unusual because I have RLS and frequently need to move to another location to sleep. She then tells me that I kept trying to touch her between her legs and I persisted until she was able to get me to "wake up." She told me I seemed really confused and she thought I was still asleep. She said she cried for quite a while and I went right back to sleep after she asked me to move to the futon. She was really upset by the whole thing and said she was afraid to sleep in the same room as me the rest of the night.

Needless to say I was completely mortified by this. This is completely out of the blue for me. I've been having pretty intense sexual dreams of late and I jump and move in my sleep but I've never done this. I'm feeling hurt and really confused right now. I have no recollection of this happening and I hate to think that my wife is scared to sleep next me. We talked and did some research and sexosomnia isn't uncommon. I've always been a strange sleeper (RLS, dreams where I've jumped on her when I thought a dog was attacking) so it's not unusual that it happened to me. I'm just really shocked because this is completely out of the blue. I am guessing it has something to do with repressed sexual frustration coming out unconsciously. In the end she said she wasn't mad at me I just worry about it happening again and any long term effects it might cause. I don't want to quit NoFap over this. I'm doing this to get rid of my PIED and make my love life better, not to cause me to be a weirdo, sleeping creeper. Anyone else have something like this happen?
